Answer:
D. AO
Step-by-step explanation:
The radius can be made with a line from a point in the circumference (end) to the middle.
Point A is on the circumference. Point O is in the middle. So, line segment AO is the radius.
Follow the order of operations.
First do what is inside the parenthesis
20 + 3(7+4) + 5 + 2(7+9)
20 + 3(11) + 5 + 2(16)
Next, do the multiplication
20 + 3(11) + 5 + 2(16)
20 + 33 + 5 + 32
Then add
20 + 33 + 5 + 32 = 90
